Bypass operation.
Although the 8800E/8801E can also be bypassed in a faulty or wet sensor condition, it is not recommended. For
safety reasons it is NOT possible to bypass the 8800E/8801E when no proper ground is detected with the standard
bypass key. A special bypass key has to be used to switch the 8800E/8801E in total bypass mode. Special
provisions should be made to make sure the truck with the compartments are discharged the build-up static
electricity. Also during loading the chassis should be properly grounded (e.g. by means of a separate earth cable).
The 8800E/8801E bypass routine is able to bypass more then one event (“stackable“ bypass).
This means every time a non permissive situation occurs (except ground verification) the rack monitor can be set
back to permissive to load by placing the bypass key in the designated location (see Bypass-key manual for
details).
The wet or faulty condition will stay visual until the plug is disconnected from the truck socket.
During bypass mode two yellow LED indicators will flash inversely and a message will also be present on the LC-
Display. The channel information will switch e.g. from W (WET) to B (Bypassed)
When the 8800E/8801E is bypassed it will automatically leave the EN13922 mode.
Note: The 8800E Rack Monitor will revert to normal operation as soon as the plug is disconnected from the truck
and ready to service the next load.
